Fans of the Chelsea soccer team went on a rampage in central Paris, making Nazi salutes and vandalizing stores before a match with Paris Saint-Germain on Wednesday night, according to a report in The Guardian.

Dozens of drunk fans were seen rioting in tourist areas, shouting racist abuse and making Nazi salutes before attacking Paris Saint-Germain fans and throwing bottles at nearby cafe-goers.

Security authorities said around 100 hooligans from each side had been "looking for each other" with the aim of causing trouble since Tuesday evening but had been kept apart by police, the Guardian reported.

French media raised concerns about possible violence earlier in the week. The website Spacefoot.com said about 300 of the expected 2,200 Chelsea fans had been flagged by police as "potentially dangerous."
